strange scrolling behavior

One of the things I don't like about the dailykos website is
that the diaries do not automatically open with comments expanded.
I realize that you can set this if you are logged in, but I usually
am reading the site without being logged in. So, when I open a
diary I have to click on the "Expand" button, wait for the page to
update, then begin scrolling usually with the slider on the right
hand side of my browser (IE9 at this time). At some point I stop
scrolling, read the diary or comments, and take my hand of the
mouse. When I want to go back to scrolling I often will hit the
down arrow key on my keyboard. At that point the webpage does
something totally unexpected. It toggles between "expand" "shrink"
and "hide". This behavior is very annoying and not something I've
experienced on any other site.

whoanellie, this might be something unique to IE9. I logged out
to see if it would happen to me, and it didn't with Firefox.

Awhile back people had a problem when they tipped a comment and
then started to scroll down the page using the arrow keys. The
tipped comment would jump over to hide! What people had to do,
until it was fixed, was after clicking to tip, click somewhere else
on the page to get the cursor out of the tip radio button.

That might work for you, until they can figure it out and fix
it. After you've click Expand, click somewhere else - just an empty
white space on the page - to get the cursor out of the Expand
button. Then try arrowing down.
